MACHINE FOR MIXING LIQUIDS.-

SPE CIPICATION forming part of Letters Patent No. 455,479, dated July 7,'1 891. Application filed September 16 1890- Serial No. 365,148- (Nomodel.)

To all whom it may concern:

Be it known that we, WILLIAM BRUEN and HENRY O. HUNT, of Newark, in thecounty of Essex and State of New Jersey, have invented certain new anduseful Improvements in Machinery for Stirring, Beating, or MixingLiquids of Any Kind, for which we desire'to secure Letters Patent of theUnited States of America; and we do hereby declare that the following isa full, clear, and exact description of the same, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

The present invention ments in churns, and has reference more parofchurns for mixing drinks, the object being to provide a simple andefficient device for operating the machine which shall be noiseless inits operation as well as ornamental.

The invention consists in certain details of construction andcombination, of parts, as will hereinafter be fully described, andfinally embodied in the clauses of the claim.

In the accompanying two sheets of drawings, in which is illustrated ourinvention, Figure 1 is a front elevation of our improved machine. Fig. 2is a top view of the same. Figs. 3 and 4 are horizontal sections, takenon line 00 in Fig. 1, of the device in two different operativepositions. Fig. 5 is an enlarged vertical section taken through Fig. 4on a line through said figure in the direction of arrow y. Fig. 6 is avertical section of a cover adapted to be used on receptacles em ployedin the machine for mixing or churning a liquid, and Fig.7 is a detailview of the belt fastener and tightener.

Similar letters of reference are employed,

to indicate corresponding several views.

In said views, y represents any suitable base, such as a counter, towhich is secured by means of suitable pins or screws .9 the base or bedplate B of the machine, preferably of cast metal, being-provided at theone end thereof with a hollow upright or standard e, which is preferablysecured to the bedplate B by means of screws'or rivets 6 as in Fig. 5.WVithin this hollow upright and formed upon the bed parts in each of thepassing through a rectly upon the upper surface 6 relates to improve.

.plate is a pedestal-bearing s, uponwhich roztates the lower end of avertical shaft. 8, said held in its vertical position by perforation inthe top of the hollow upright 01' standard, within which perforation itis free to rotate. Resting diof the up right e is a spirally-groovedpulley P, firmly secured to the shaft .9, as shown, and secured upon itsupper end is a receptacle-receiving platform P, as clearly illustratedin Figs. 1 and 5. This platform is preferably cast separate from thespirallygrooved pulley and is secured thereto in any convenient manner,so that it will rotate with said pulley and shaft.

shaft being At the opposite end of the bed-plate B is formed a secondupright or standard 6, provided with an upwardly-projecting pin or pivote, on which is pivotally arranged'a hand-lever L, secured thereon bymeans of a short pin e passing through a hole 6 in the pin 6', whichprevents any displacement of the lever While operating the machine. Saidlever is bifurcated, comprising the two arms land Z, which extend onopposite sides of the shafts, and an ordinary belt B, which is passed intwo or three coils around the spiral pulley P, is secured to the arms Zand Z of the lever L by means of the fastening devices (1 and 01,respectively. As will be seen from the several figures, said platform Pis provided with any desirable number of receivirig-compartments P inwhichcan be placed the fluid-receptacles 7' and 9", which may be theordinary glass tumbler when used for or they may be of any suitableconstruction and size when the device is used as a churn.

Upon each of said liquid-receptaclesare placed suitable covers 0 and 0which are provided with packing-rings 0 as clearly shown in Fig. 6,which rings are arranged in an annular recessed portion h of the cover,as willbe evi dent from said figure.

hen the receptacles or glasses r and 4"" have been placed in positionupon the platform P, the covers 0 and c are arranged upon thereceptacles so that the packing-ring 0 comes in contact with .thesurrounding edge of the open part of the receptacle.

Upon the upper end 8 of the shaft 3 and sliding upon the part 8 which isof smaller diameter than the part 8 we have arranged den reversedmovement of the lever L.

a crossbar 0, provided with a hub 1-1, which is fitted upon and freelyslides on the part 5 of the shaft .9, whereby said cross-bar is capabioof a vertical as well as a rotary movement upon the shaft 3. On thelower side of the cross-bar the hub H is enlarged, providing a chamber7L2, within which has been placed an ordinary coil-spring a, as will beseen from Fig. 5. When the covers 0' and 0 have been placed on thereceptacles r and a" in position upon the platform I the ball ends 0 ofthe cross-bar o are placed within a corresponding depression 0 in thecenter of each cover 0' and c and the cross-bar is then firmly tighteneddown upon the covers by means of a screw n, which canbe made to move upand down upon the threaded portion 02 on the part 5 of the shafts. Thisthreaded portion of the shaft is also provided with a nut a, whichlimits the upward movement of the screw 01, as will be evident. Thus bymeans of this screw and the cross-bar c the flexible packing-rin gs inthe covers are tightly secu red down upon the upper edges of theliquid-receptacles, thereby securely holding them in position on theplatform P and preventing any leakage from the liquid-receptacles whenthey oscillate about the shaft 3.

From Figs. 1, 2, ct seq, it will be seen that the arm Z of the lever Lis provided with a handle h. The belt B, as has been stated in theabove, is fastened to the arms Z and Z by means of the fastening devices(:1 and (1, respectively, the fastener 61' being simply a small loopwhich hooks over a catch cast on the arm Z, as shown at a in Fig. l. Thefastener cl at the other end of the belt is provided with a metallic endpiece (:1 having a screw-thread d passing through a chambered portion 1on the end of arm Z. Within this chamber is placed a tension-sprin g 'i,and upon the projecting and threaded end of the metallic piece 01rotates an ordinary thumbscrew 42. Thus it will be evident that when thebelt is in place around the spiral pulley on the shaft, and the end dhas been inserted through the perforated and chambered end of the arm1-, the nut is screwed up, thereby bringing the proper tension on thebelt B. Now when the power is applied to the handle it on the lever Lsaid lever swings upon the pivotal post e and thereby receives anoscillating and ahorizontal movement. At the same time the belt operatesthe pulley P, and with it the shaft and platform P, causing anoscillatory movement of the several parts.

The belt may be wound several times around the spirally-grooved pulley,thereby increasing the traction of the belt, the same working withoutchafing, and at the same time preventing the slipping during the sud-The spring 71 Within the chamber Z on the arm Z also helps to reduce thetension on the belt B while the same is suddenly reversed. Thus itwill-be seen that the fastening device 61 serves the double purpose ofreducing the tension while reversing the rotary motion of the machine,and also to take up any slack of the belt.

The advantages of the present form of construction are evident. Byimparting an oscillatory movement to the actuating-lever thelicpiid-receptacles are rapidly rotated in opposite directions, whichhas the effect of causing the liquid in each receptacle to be whirledaround first in one direction and then suddenly in the oppositedirection, causing the contents to be thoroughly mixed, and when usedfor churning milk the globules of milk sufficiently and effectuallygrind against each other and liberate the cream, producing butter in avery short space of time.

Having thus described our invention, what we claim is r l. Thecombination, with a bed-plate provided with a vertical shaft and aliquid-receptacle-bearing platform, of an oscillating andhorizontally-moving lever arranged on a support on said bed-plate andprovided with a belt which is wrapped around the shaft for causing thesame and the liquid-receptacle platform to oscillate about the verticalaxis of said shaft, for the purposes set forth.
